Eat on the go primal? Help please

My DH is semi-on board with primal/paleo, he won't be totally strict though. Right now he is working as a security guard, and works 12-hour shifts without a set "lunch break", so he has to eat in his car. He does not have a place to heat up food. In the past I have done things like sandwiches and burritos, but those are so not primal.

What are some primal options to pack in a lunch that can be eaten on the go? He is looking to gain, not lose weight, he is wiry and thin. Help please!

I typically pack big ass salads for cold lunches. Include plenty of meat and a nice oily dressing, and add nuts or cheese if you still need to increase the calories. In terms of cooked food, some leftovers are better cold than others. BBQ chicken is delicious cold, and you can round out the meal with some cut up veggies with dip. Also, keep in mind that anything you can eat on a sandwich or in a wrap can be put in a container and eaten with a fork (or your hands, if you prefer).

People say I am on a "crazy" diet. What is so crazy about eating veggies, fruits, seafood and organ meats? Just because I don't eat whole wheat and processed food doesn't make my diet "crazy". Maybe everyone else with a SAD are the "crazy" ones for putting that junk in their system.
